Abstract: Current and upcoming wide-field large-scale structure surveys will enable precision measurements of various observables of large-scale structure, such as weak lensing, galaxy clustering, and the abundance of galaxy clusters. These observables probe different aspects of cosmic structure formation, and combining them improves constraints on cosmology significantly. However, these observables probe the same underlying density field, and the information content is correlated. Additionally, they share correlated (astrophysical and observational) systematic effects. In this talk I will highlight the analysis concepts recently developed for the joint analysis of probes of large-scale structure for the Dark Energy Survey, and give an outlook on cosmology analysis plans and challenges for LSST and WFIRST.
